创建文件(makeTexFile.py)

创建一个尚不存在的文件名，然后由用户输入数据写入到文本文件。

#makeTextFile.py -- create text file

import os

#get filename

while True:

          fname = raw_input('Enter file name:')

          if os.path.exists(fname):

                 print "ERROE: '%s' already exists" % fname

          else:

                 break

#get file content (text) lines

all = []

print "\nEnter lines ('.' by itself to quit).\n"

#loop until user terminates input

while True:

         entry = raw_input('> ')

         if entry == '.':

                 break

         else:

                all.append(entry)

# write lines to file with proper line-ending

fobj = open(fname, 'w')

fobj.write('\n'.join(all))

fobj.close()

print 'DONE!'
